How do I install the bobbin wound with thread?
(1) This model (2) Other models (3) 11.5 mm (approx. 7/16 inch) |
(1) Mark on the handwheel |
(1) Presser foot lever |
(1) Cover (2) Slide button |
Make sure you set the bobbin so the thread unrolls in the right direction. If the thread unrolls in the wrong direction, it may cause the thread tension to be incorrect or break the needle.
(1) Tension-adjusting spring |
If the thread is not correctly inserted through the tension-adjusting spring of the bobbin case, it may cause incorrect thread tension.
Replace the cover so that the end of the thread comes out from the left side of the cover (as shown by the line in the diagram).
